Mary Douglas Leakey was recognized in her lifetime as one of the world’s most distinguished fossil hunters. In 1974 Mary BEGINS work at Laetoli, 30 miles from Olduvai Gorge. It is here that Mary and her team found amazingly well preserved hominid footprints in volcanic beds, known as tuffs. The footprint tuff of 1976 has a potassium argon date of 3.5-3.8 mya, evidence of upright walking that supported Donald Johansen's find, Lucy, also known as Australopithecus Afarensis, though Mary Leakey has rejected this( she believe that the belong to the genus homo). Eighty feet of trail had been uncovered by 1979, leaving researchers to speculate that it was three hominids, possibly a family, that left their mark millions of years ago.
Important reasons for studying history are recognizing patterns, connecting the past to the present and revealing past contributions of civilizations.
The arrest of a criminal suspect.
If you've ever watched a television crime drama, you've heard the "Miranda warning" -- or at least the beginning of it: "You have the right to remain silent. Anything you say can and will be used against you in a court of law. You have the right to an attorney ...." There's a couple more sentences to the warning, but TV shows often cut to the next scene before hearing the arresting officer finish their recitation of the full warning.
Miranda v. Arizona was a Supreme Court case decided in 1966. Ernesto Miranda was accused of kidnapping and raping a woman. He confessed to the crime when interrogated by police, but attorneys argued that he did not fully understand his 6th Amendment rights. After the decision in Miranda v. Arizona, it has become standard procedure in all arrests that the arresting officers must clearly state the accused person's rights -- their "Miranda rights," as they have become known.
